Preheat your oven to 325°F (160°C). Line an 8-inch square baking dish with parchment paper, leaving some overhang for easy removal later.
In a mixing bowl, combine graham cracker crumbs, melted butter, and 2 tablespoons sugar. Stir until the mixture resembles wet sand.
Press the crumb mixture firmly into the bottom of the prepared baking dish to form an even crust. Bake for 8-10 minutes, then remove and let it cool for a few minutes.
In a large mixing bowl, beat the softened cream cheese with 1 cup sugar until smooth and creamy, about 2-3 minutes.
Add the eggs one at a time, mixing well after each addition.
Mix in the sour cream, matcha powder, vanilla extract, and a pinch of salt until well combined and there are no lumps.
Pour the matcha cheesecake filling over the cooled crust and spread it evenly.
Bake in the preheated oven for 25-30 minutes or until the edges are set and the center still has a slight jiggle.
Turn off the oven and crack the door slightly, allowing the cheesecake to cool in the oven for another 10 minutes to prevent cracking.
Remove from the oven and let it cool to room temperature, then refrigerate for at least 4 hours or overnight for optimal firmness.
Once chilled, use the overhanging parchment paper to lift the cheesecake out of the dish. Cut into squares and enjoy!
Notes
Dust the tops of the cheesecake squares with extra matcha powder before serving and garnish with fresh berries or a dollop of whipped cream for added flair.
